During the development process of Wilson Combat AR-15 rifles in .458 SOCOM we have determined that a properly modified Lancer L5AWM magazine is the most reliable feeding device for the widest variety of ammunition. Lancer’s Advanced Warfighter Magazines combine the best of both worlds for the ultimate hybrid rifle magazine. Perfect for civilians, law enforcement, and the military alike, L5AWM delivers innovative features, improved internal geometry, and an in-house design that takes performance and reliability to the next level. This magazine is ideal for bench rest and prone shooting.

These Lancer 5.56 L5AWM magazine feed lips have been carefully modified in our shop to hold the .458 SOCOM higher in the tube which allows the use of a wider variety of projectile shapes. We also cut a deeper clearance at the front of the magazine body to allow the big SOCOM case to better clear the magazine during the feeding cycle.
